Lips look complicated, but they're built from a few simple shapes. The trick is starting with the center line (the line where the lips meet) — it's the most important line, since it defines the whole expression.
What you need: a pencil, an eraser (a kneaded eraser is great for highlights), and paper.
Step-by-step:
- Draw the center line. Sketch a horizontal line with a gentle wave — it dips slightly in the middle and curves up at the corners. This is the line where the two lips meet, and it's usually the darkest line in the finished drawing.
- Add the Cupid's bow. Above the center line, draw the "M" shape of the upper lip — two soft peaks in the middle with a small dip between them, tapering down to each corner.
- Draw the lower lip. Below the center line, draw a single, fuller curve. The lower lip is usually thicker and rounder than the upper lip.
- Check proportions. The lips are widest at the center and taper to the corners. Lightly mark the corners first so both sides stay even.
- Add shading for volume. Lips are three-dimensional, so shade:
- Darkest along the center line where the lips meet.
- Darker at the corners and along the bottom edge of the lower lip.
- Lighter on the fullest parts that catch light.
- Add a highlight. Use an eraser to lift a soft highlight on the middle of the lower lip (and just above the Cupid's bow) — this makes them look full and glossy.
- Add texture. Draw fine vertical lines following the curve of the lips for a natural texture, keeping them soft and light.
Tips: Keep the outer edges soft rather than a hard outline — real lips blend into the skin. And remember lips curve around the face, so they aren't flat.
